Abstract: A display device includes a substrate including a display area and a non-display area adjacent to the display area, a pixel disposed in the display area, a first voltage line disposed in the non-display area and supplying a first power supply voltage to the pixel, a second voltage line disposed in the non-display area and supplying a second power supply voltage to the pixel, the second voltage line being apart from the first voltage line, and a metallic pattern disposed between the first voltage line and the second voltage line. A shortest distance between the first voltage line and the second voltage line is greater than a width of the metallic pattern.

Abstract: A display panel includes a base layer, a circuit layer, and a pixel layer. The base layer includes a plurality of light emitting areas, and a plurality of transmitting areas to transmit light incident thereto. The circuit layer includes a plurality of switching devices disposed on the light emitting areas, and a plurality of photosensors disposed on the transmitting areas. The pixel layer includes a light emitting element to emit light based on reception of a current from at least one of the plurality of switching devices. The light emitting element overlaps with one of the plurality of light emitting areas. At least one of the plurality of phototosensors is configured to receive a portion of external light reflected from an external object after transmission of the external light through at least one of the plurality of transmitting areas.

Abstract: A display device includes a base layer, first pixels, second pixels, a power supply line (PSL), a power supply voltage supply circuit (PSVSC), and a feedback wire (FBW). The base layer includes a display area (DA) and a non-display area (NDA) adjacent to the DA. The DA includes a first pixel area (PA) including first pixels and a second PA including second pixels. The second PA protrudes from the first PA. The PSL extends in at least a first direction in the DA. The PSL receives a first power supply voltage (PSV) through a first end of the PSL, and supplies the first PSV to the first and second pixels. The PSVSC supplies the first PSV to the PSL through the first end. The FBW is electrically connected to a second end of the PSL disposed in the second PA. The FBW feeds back the first PSV to the PSVSC.
